Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
83 words
A cwater drainage system for removing excess water from a section of highway having a plurality of paved lanes and unpaved shoulder areas of ground on the outside of said lanes comprising, in combination: at least one water permeable structure penetrating said ground within said shoulder areas connecting with an underground source of water; and at least one water retaining basin formed in said shoulder areas providing temporary storage of said excess water and directing said excess water into said water permeable structure.
Claim 2
Dependent Claim
83 words
A cwater drainage system for removing excess water from a section of highway having a plurality of paved lanes and unpaved shoulder areas of ground on the outside of said lanes comprising, in combination: at least one water permeable structure penetrating said ground within said shoulder areas connecting with an underground source of water; and at least one water retaining basin formed in said shoulder areas providing temporary storage of said excess water and directing said excess water into said water permeable structure.
Claim 3
Dependent Claim
77 words
A water drainage system for removing excess water from a section of highway having a plurality of paved lanes with an unpaved median portion therebetween comprising, in combination: at least one water permeable structure penetrating the ground within said median portion connecting with an underground source of water; and at least one water retaining basin formed in said median portion providing temporary storage of said excess water and directing said excess water into said water permeable structure.
Claim 4
Dependent Claim
77 words
A water drainage system for removing excess water from a section of highway having a plurality of paved lanes with an unpaved median portion therebetween comprising, in combination: at least one water permeable structure penetrating the ground within said median portion connecting with an underground source of water; and at least one water retaining basin formed in said median portion providing temporary storage of said excess water and directing said excess water into said water permeable structure.
Claim 5
Dependent Claim
16 words
The system of claim 2 wherein said water permeable structure comprises a dry well containing sand.
Claim 6
Dependent Claim
47 words
The system of claim 2 wherein said highway includes shoulder areas on opposite sides of said lanes with respect to said median portion and including at least one of said water permeable structures and at least one of said water retaining basins formed in said shoulder areas.
Claim 7
Dependent Claim
27 words
The system of claim 2 including a plurality of dams across said median portion forming a plurality of said water retaining basins which sectionalize said median portion.
Claim 8
Dependent Claim
50 words
The system of claim 2 wherein said highway includes shoulder areas on opposite sides of said lanes with respect to said median portion and including water conveying means transversing said lanes and connected with said basin in said median portion for directing water from said shoulder areas into said structure.
Claim 9
Dependent Claim
14 words
The system of claim 2 wherein said water permeable structure comprises an open well.
Claim 10
Dependent Claim
13 words
The system of claim 2 wherein said structure is connected to an aquifer.
Claim 11
Dependent Claim
14 words
The system of claim 2 wherein said structure is connected to an underground stream.
Claim 12
Dependent Claim
24 words
The system of claim 2 wherein said water permeable structure comprises a dry well containing a water permeable coarse aggregate material such as gravel.
Claim 13
Dependent Claim
24 words
The system of claim 10 including layers of sand interspersed with said coarse aggregate material for filtering said excess water permeating said dry well.
Claim 14
Dependent Claim
79 words
The system of claim 2 wherein said water permeable structure comprises a well including: a first water permeable pipe extending downward through said well; a lining of water permeable coarse aggregate material surrounding said first pipe; and a cover over said first pipe and said lining having an opening therein for directing water into said first pipe whereby silt can be removed from said water and collected in said first pipe prior to being discharged into said underground source.
Claim 15
Dependent Claim
42 words
The system of claim 12 including a second water permeable pipe removably mounted within said first pipe, said water being directed into said second pipe by said opening whereby said silt can be removed from said structure by removing said second pipe.
Claim 16
Dependent Claim
51 words
The system of claim 2 wherein said water permeable structure comprises a dry well containing a water permeable coarse aggregate material therein; and said basin includes a plurality of trenches filled with said aggregate material and having a covering of soil thereover, said trenches connecting said basin to said dry well.
Claim 17
Dependent Claim
28 words
The system of claim 14 including a bed of said coarse aggregate material surrounding said dry well for directing water therein, said trenches being connected with said bed.
